1
Start in a side plank position with your body in a straight line from head to feet, supporting yourself on one forearm and the side of one foot, with the dumbbell held at hip level
2
Engage your core and stabilize your torso by tightening abdominal muscles. Position the dumbbell in one hand at hip level while maintaining a neutral spine and level hips
3
Slowly rotate your torso forward and downward, allowing the dumbbell to move toward the ground in a controlled arc as you flex the obliques and rectus abdominis through rotation and crunch movement
4
Return to the starting side plank position by contracting the abdominals and rotating the torso back to neutral, bringing the dumbbell back to hip level and restabilizing the side plank
